• 化学的特性

  Triphenylmethanol is a white powder or colorless, isolated crystals that are soluble in alcohol, ether, and benzene. It turns dark yellow when dissolved in concentrated sulfuric acid, colorless when dissolved in glacial acetic acid, and is insoluble in water and petroleum ether. It distills at 360-380°C without decomposition.

• 使用

  Triphenylmethanol is used as a reagent in the research laboratory. It acts as an intermediate in the production of the commercially useful triarylmethane dyes. It is used in the preparation of triphenylmethane. It is also used as an antiproliferative agent. Further, it is used in the preparation of two-electron reduction product of pyrylogen. In addition to this, it reacts with triphenylphosphine oxide to form a 1:1 molecular complex. It serves as a specific clathrate host for methanol and dimethyl sulphoxide and forms clathrate inclusion complexes.
  Triphenylmethanol was used in the synthesis of of the two-electron reduction product of pyrylogen.
  It undergoes reduction to triphenylmethane by 9, 10-dihydro-10-methylacridine in the presence of perchloric acid.

• 製造方法

  Triphenylmethanol synthesis: Triphenylmethanol was prepared by the action of benzene with carbon tetrachloride in the presence of Aluminum chloride, followed by acidification and hydrolysis.
  Triphenylmethanol can also be prepared by the reaction of phenylmagnesium bromide with methyl benzoate (instead of benzophenone).
  Synthesis of Triphenylmethanol

• 反応性

  The first one is the formation of the triphenylmethyl bromide from the reaction of triphenylmethanol with hydrobromic acid.
  The second reaction is the formation of an ether from the reaction of triphenylmethanol with methanol in acidic conditions.
  

• 一般的な説明

  Triphenylmethanol forms 1:1 molecular complex with triphenylphosphine oxide. It is a specific clathrate host for methanol and dimethyl sulphoxide and forms clathrate inclusion complexes. It undergoes reduction to triphenylmethane by 9, l0-dihydro-10-methylacridine in the presence of perchloric acid.

• 材料の用途

  Triphenylmethanol (TPOH) is a non-fluorescent compound that emits strong fluorescence in an aggregate state or on a solid surface after irradiation by UV light at 254 nm (UV1). Interestingly, the photo-induced fluorescence of TPOH was quenched when irradiated by UV light at a longer wavelength of 365 nm (UV2) and further repeatable on and off by UV1 and UV2, respectively. The reversible activation and deactivation of fluorescence at a solid surface could be repeatable at least 5 times. TPOH is thus applied for rewritable photopatterning tuned by UV light[1].

• 純化方法

  Crystallise the carbinol from EtOH, MeOH, CCl4 (4mL/g), *benzene, hexane or pet ether (b 60-70o). Dry it at 90o. [Ohwada et al. J Am Chem Soc 108 3029 1986, Beilstein 6 IV 5014.]
